The Burnout Concept as a Theoretical Framework for Investigating the Caregiving Impact of Relatives of Patients withAddictive Disorders

Background Relatives of patients withaddictive disorders often face significant difficulties in their daily lives. Although the burnout concept is currently considered a significant and promising theoretical framework for studying family members who care for chronically ill patients, its application has encountered considerable difficulties in the area of addiction treatment. Objective This article explores the methodology for studying the psychological issues arising in families affected by addictive disorders. We analyzed the social, economic, and cultural conditions of the different study models developed in this field, and identified the difficulties hindering the acceptance of the burnout concept as a theoretical construct for investigation. Results There are several main obstacles to the burnout concept’s application to studying the psychology of addictive patients’ families. These obstacles are: 1) a stigmatizing attitude toward the relatives, labelling them as dysfunctional/codependent, or merely passive recipients adjusting to stressful and challenging circumstances; 2) a sole focus on the destructive elements of the “informal caregiver — addicted patient” relationship dynamics; 3) underestimation of relatives’ willingness, experience, and knowledge in the care of their addicted family member and failure to recognize their right to participate in treatment decision-making; and 4) lack of specialized tools for assessing burnout and its opposite pole — the engagement of addicts’ relatives during the patients’ care. Conclusion Application of the burnout concept as a theoretical framework allows us to reformulate many psychopathological phenomena described in the family members of addicts, and expands the perspective of psychotherapy by providing the opportunity to conduct interventions to improve relatives’ functioning as caregivers. This, in turn, will contribute to the effectiveness of treatment outcomes for bothaddicts and their families.


Introduction
Addictive disorders are chronic diseases which oft en signifi cantly undermine the addict's physical health and can have severe psychological and social consequences both for the patient himself and for his/her social circle. Most addicts (at least in the initial stages of their disorder) have a family. Family members interact with the addict to varying degrees, depending on their position or role in the family. Family members usually make attempts to help the patient cope with the disease and the most involved relatives, who are typically women, experience a greater impact, which results in detrimental eff ects and suff ering for themselves.
Studies have shown that relatives involved in interacting with the addicted patient typically experience severe anxiety and depression. Th ey may experience helplessness, anger, guilt, or constant concern for the patient's physical and mental wellbeing. A signifi cant reduction in the quality of their social life, disruption of close family communications, and development of somatic illnesses caused by stress in connection with the illness of a loved one, are oft en studied in addicts' relatives (Copello et al., 2010b;Orford et al., 2005Orford et al., , 2010Settley, 2020). However, the contribution of a family caregiver to maintaining the patient's well-being is frequently underestimated due to the attitudes of the professional community which interacts with addicts' relatives. Th ese attitudes can be shown by specialists apparently ignoring, or even disapproving of, family care.
In Russia, relatives of patients with addictive disorders are usually viewed within the framework of the codependency concept. Th is concept appeared in Russia along with the Minnesota model of addiction treatment. Currently, various adaptations of the 12-step program, based on the Minnesota model, are being used almost everywhere in clinics engaged in the treatment and rehabilitation of addicted patients. According to the codependency model, the relatives' care for a patient is perceived as unconscious compensation of their own personal dysfunction. Th is means that such care has psychological benefi ts and should be considered as a psychotherapeutic target.
Stress-oriented models, which are common abroad, consider interaction between the family and the addict as a stress factor that can cause strain on family members, leading in some cases to somatic and/or psychic disorders. Relatives' care in such a context is seen as harmful for their own health, and thus undesirable.
In both theoretical models currently used for the studying of addicts' relatives, the principal orientation calls for increasing the distance, or even urging separation, between informal caregivers and addicts. Th us, the very possibility of a caregiving status for the addict's relatives is questioned. But actually, "family members are frequently an unpaid and unconsidered resource providing health and social care to their substance-misusing relatives" (Copello et al., 2010b, p. 67), which defi nes them as informal caregivers of chronically ill patients.
Th e term informal caregiver, at the moment, is widely applied in sociology, psychology, and nursing. Its defi nition varies depending on the application area. Analysis of the literature allows us to give the following defi nition: an informal caregiver is one who has a social relationship (spouse, parent, child, other relative, neighbor, friend, etc.) with the care recipient (dependent and in need of care due to various circumstances) and provides unpaid care on an ongoing basis or as required 2021a).
Th e alleged incompatibility of kinship relations with the caregiver's role within the framework of the theoretical models used in the fi eld of addictive disorders, on the one hand, and the actual existence of relatives in this role on the other, represent the main contradiction within the current situation, and call for necessary changes.
Analysis of the literature has shown that one of the important principles that currently explains the psychology of informal caregivers is the concept of burnout 2021a). Nowadays this concept is not only applied in the occupational context, but is also used in a wider sense to describe "caregiver-carerecipient" relationships, as in the parent-child or "caregiver-chronically ill relative" area (Gérain, & Zech, 2019;Lebert-Charron et al., 2018;de Souza Alves et al., 2019). Th e burnout concept is described as a considerable and promising theoretical basis for empirical and interventional studies (Gérain, & Zech, 2019). Actively developing research on the burnout observed in caregivers for somatically and mentally ill patients paradoxically has not been applied to the studies of the psychology of addictive patients' informal caregivers. Th us, the question arises: what prevents the theoretical concept of burnout from being explored in the study of addicts' caregivers?
As we already mentioned, non-recognition of relatives as caregivers may be one of the reasons for a signifi cant delay in applying the burnout concept in the fi eld of addictive disorders. In present work we analyze the possibilities and barriers of employing the concept of burnout as a theoretical framework for studying the complex psychological problems experienced by relatives taking care of addicted family members. For better understanding of these possibilities and barriers, we fi rst present a brief overview of the burnout concept, its implementation outside the occupational context, and the main tools of its measurement, as well as the theoretical models that are most oft en used for studying addicts' relatives.

Methods
Based on a review of the literature and our own clinical experience, we explored some methodological issues concerning investigation of the caregiving impact of relatives of patients with addictive disorders. A literature search for publications indexed in Cochrane Library, EMBASE, Web of Science, Scopus, and PsycINFO databases was conducted between 2015 and 2021. Th e gray literature investigation included searches in databases of theses and manuscripts such as OATD and NDLTD. Additional manual search was based on expert consultations and references in specifi c journals and books. Articles were analyzed to see if they described the burnout concept and its implementation outside the occupational context, on relatives or families aff ected by addictive disorders, especially in the aspects of psychological consequences of informal caregiving. Th e data extraction and following analyses relied on expert knowledge, which allows in-depth understanding and synthesis of theories and links between them (Hannes, 2011).

Th e concept of "burnout"
Emergence and development of the burnout construct Th e phenomenon of 'burnout' was fi rst described in the works of Freudenberger (1974) and Maslach (1976). Th ey discovered, independently of one another, that social workers as well as customer service workers oft en feel emotionally exhausted, and develop negative attitudes toward their clients or patients. Th ese observations served as the basis for the subsequent development of the idea of professional burnout, which has become internationally recognized as a concept to describe this particular type of physical, emotional, and mental exhaustion and stress.
It is important to note that the clinical observations on which the original burnout concept were based came from the experiences of volunteers at the St. Mark's Free Clinic in New York's East Village -a free clinic for drug addicts and homeless people. Freudenberger used the term to describe the gradual loss of motivation, lowered commitment, and emotional depletion among the volunteers who were caring for illicit drug abusers (Freudenberger, 1974).
Summing up their observations, Maslach and her colleagues developed a tridimensional concept of burnout: 1) emotional exhaustion; 2) depersonalization; and 3) reduced personal accomplishment. In addition, the authors created the Maslach Burnout Inventory (MBI), which enabled the assessment of an individual's experience of occupational burnout (Maslach, & Jackson, 1981;1998).
Emotional exhaustion refers to feelings of being overextended and depleted of one's emotional and physical resources and is considered a basic component of the syndrome. Depersonalization (cynicism) represents a negative, cynical, or distant attitude toward people encountered in professional life. Th is negative, excessively detached response to various aspects of the job represents a motivational, interpersonal dimension of burnout. Finally, reduced personal accomplishment refl ects a sense of decrease in one's own competence and eff ectiveness, and is a self-evaluative dimension of burnout (Maslach, 1998).
Th e three-factor structure of the concept developed by Maslach was applied unchanged to diff erent professional groups and cultures (Leiter, & Schaufeli, 1996;Schaufeli et al., 2009;Qiao, & Schaufeli, 2011). However, a number of researchers questioned the presence of any common etiology of the emotional exhaustion, depersonalization, and reduced personal accomplishment and claimed that each of the components could develop independently of the others (Golembiewski, & Boss, 1992;Shirom et al., 2005).
Th e component of reduced personal accomplishment is particularly subject to criticism. A number of empirical studies have demonstrated that the personal accomplishment scale poorly correlates with the scales of emotional exhaustion and cynicism. Relying on this data, Green, Walkey, and Taylor concluded that exhaustion and cynicism are the core dimensions of burnout (Green et al., 1991;Schutte et al., 2000).
Some other theorists consider burnout a one-dimensional concept (Kristensen et al., 2005;Shirom et al., 2005). According to these authors, exhaustion is the main symptom of burnout; in fact, it is its equivalent.
In recent decades there has been a shift in research focus from burnout towards engagement in work. Although Maslach and Leiter (1999) assumed that engagement and burnout constitute the continuum of work-related well-being, the concept of engagement and its measurement was not suffi ciently developed by them. According to Maslach, low scores on the MBI exhaustion and cynicism scales, and a high score on the professional accomplishment scale, refl ect engagement phenomena. Subsequent studies have argued that burnout and engagement need to be estimated independently (González-Romá et al., 2006).
At the present time, work engagement is a multidimensional concept. Engagement in work is defi ned as a positive, fulfi lling, work-associated state of mind. It is typically characterized by three features: vigor, dedication, and absorption (Schaufeli et al., 2002). Vigor is characterized by high work capacity and fl exible thinking (i.e., creativity) in the work process. Dedication is associated with the feeling of meaningfulness, enthusiasm, inspiration, and pride. Absorption implies complete concentration, such as when a person is so deeply engrossed with his/her work that time passes by unnoticed.
For measurement of work engagement, a self-report questionnaire called the Utrecht Work Engagement Scale (Schaufeli, & Bakker, 2003) is widely used. Research has shown that exhaustion and vigor, as well as cynicism and dedication, each constitute their own continuums, which are dubbed energy and identification, respectively (González-Romá et al., 2006).
Analysis of the concept's current development shows that, in spite of the fact that burnout is well established in psychosocial research and describes a number of important psychosocial problems, its defi nition and operationalization are still in the process of clarifi cation.

Application of the burnout concept in the fi eld of interpersonal relations outside the occupational context
Th e issue of the applicability of the burnout concept outside the fi eld of professional activity has been discussed for some time. Some authors believe it can only be applied in a work-related context and is uniquely related to occupational exhaustion (Maslach, 1998;Schaufeli et al., 2009). Others describe the phenomenon of burnout as a condition of physical, emotional, and cognitive exhaustion resulting from continued exposure to emotionally straining situations which can occur in various circumstances, not exclusively in a work environment (Pines et al., 1996;Kristensen et al., 2005).
Th e fi rst papers focusing on the study of burnout as a theoretical concept within the analysis of family relations appeared in studies by Ekberg, Griffi th, and Foxall (1986). Th eir studies appeared to indicate that spouses of chronically ill patients had symptoms similar to those of the burnout that was typical of formal caregivers such as nurses. Th ree years later, Pelsma (1989) stated that parental burnout also existed and off ered an adjusted version of an MBI questionnaire to measure it.
However, more extensive and focused research of informal caregivers' burnout started aft er the millennium year 2000 (Norberg, & Green, 2007).
Prolonged disregard for the need to investigate the psychology of the large group of people exposed to severe stress resulting from their taking care of a chronically ill family member and interacting with them, led to some clear methodological gaps in this fi eld of study. Th is type of disregard is perhaps to be expected within the usual social and cultural norms of society (Franza et al., 2016). Th is situation, however, is undergoing signifi cant changes. In particular, the notion that care for a disabled person close to you is a normal duty for a family member that should be performed out of love for them, has been challenged. Also, the belief that care for the disabled relative should be undertaken by a family member, no matter the caregiver's external circumstances, mental state, or ability to cope, is no longer considered dogma.
Th ere have been sociocultural transformations over recent decades which have signifi cantly aff ected the institution of the family and the role of women in family interactions. Besides this, the ongoing medico-social process of deinstitutionalization has contributed to observable changes. Th e transfer of disabled people from institutions, such as hospitals, back to their families and communities to help with the reduction of inpatient beds and lengths of hospital stays, has heightened the visibility of informal caregivers' input. In combination, these two tendencies have signifi cantly changed the situation relative to the pressures and social norms of caregiving being the "sacred" duty of a patient's family, and have produced the need to understand and take into account the eff orts and costs of relatives caring for a chronically ill family member.
Currently, the theoretical concept of burnout is widely used in the context of the relationship between caregiver and care-recipient. More precisely, it is used in the study of "parent-child" relations and the relationship between the informal caregiver and the chronically ill patient.
In the fi eld of "parent-child" relations, researchers have been focusing on the problem of parental burnout in the process of a child's upbringing, and highlighting an increased risk of burnout among parents caring for children suff ering from chronic somatic or mental disorders (Roskam et al., 2018;Norberg, & Green, 2007;Lebert-Charron et al., 2018).
At the present time signifi cant data has also been collected on the burnout of informal caregivers who take care of adults with various somatic or mental disorders. Th e results of numerous investigations have shown that the burnout syndrome can negatively aff ect caregivers' quality of life and general health, as well as predict the emergence of emotional disorders (Gerain, & Zech, 2019; De Souza Alves et al., 2019).

Lack of specialized tools for measuring burnout in the fi eld of interpersonal relations outside the occupational context
Th ese days, when researchers are assessing burnout among family members caring for chronically ill relatives, the vast majority employ adapted versions of the MBI or the Shirom-Melamed Burnout Questionnaire (Lebert-Charron et al., 2018;Norberg, & Green, 2007;de Souza Alves et al., 2019). Both questionnaires were originally aimed at studying professional burnout. In the available literature, we found only a few studies that were not solely focused on the adaptation, but on the development of specialized tools for measuring burnout in family relationships (Kmit et al., 2018;Roskam et al., 2018;Shishkova et al., 2021a, b).
Analysis of the measuring tools currently used to diagnose burnout in the fi eld of family relations has revealed a number of signifi cant drawbacks. First is the fact that most of them originally came from the professional arena and were re-purposed for the fi eld of interactions between chronically ill patients and family caregivers. To consider burnout a general condition of the psyche without taking into account its causes does not enable one to consider the specifi c features of family relations. Direct transfer of the burnout concept and its assessment tools from the professional area to family relationships does not seem to be suffi ciently substantiated and thus needs to be adjusted in light of diff erent environments and relationship contexts. Secondly, existing methods of analysis are based on the diagnosis-centered approach, where analysts suggest a set of statements representing symptoms of burnout. Th e assessment score in these cases only represents the summation of destructive behaviors and processes, without relating them to the resources of the caregiver. Th is is in contrast to the contemporary view on the concept of burnout that points to the signifi cance of investigating its opposite, engagement.
In the caregiving context, vigor, for example, can represent a sense of adequate energy to solve the issues connected to the treatment and maintenance of the wellbeing of a chronically ill relative. Th e caregiver's sense of fulfi llment and meaningfulness through their care work can accordingly be considered dedication. So, the development of specialized tools could be considered one of the most vital changes required in research of "engagement-burnout" concepts outside the occupational context. Th e availability of specialized assessment measures, in turn, will allow study of the conditions and factors that contribute to, or prevent, the informal caregivers' burnout and engagement.
Th us, the analysis of the current development of the burnout concept and measuring tools used for burnout assessment reveal signifi cant obstacles to the concept's application to the study of relationships in the families of addicts. Th ese obstacles are primarily related to a certain immaturity of the construct as applied to interpersonal relations outside the occupational context. As we have seen, within the framework of family relations, the burnout construct is focused only on the defi ciency component. Th is limitation determines the ineffi cacy of the existing assessment tools, as they do not correspond to the burnout concept's current development. Th e contemporary burnout-theoretical construct requires the inclusion of engagement, which constitutes the opposite of the burnout pole and refl ects constructive personal activity. Another problem is the neglect of the specifi city of the interpersonal relationships that arise between the caregiver and care recipient.
Th e immaturity of the construct as used outside the occupational context, and the methodological inadequacy of the applied tools, act as obstacles to integrating the burnout concept into studies of the psychology of the addictive patient's family.

Th eoretical models mainly used for studying addicts' relatives. Challenges of burnout concept integration
Th e concept of codependency Th e concept of codependency, which gained popularity in the 1970s, emphasizes the personal defi ciencies and destructive behavioral patterns of addicted patients' relatives. Th ese patterns are considered to interfere with the therapeutic and rehabilitation process and are to be overcome by breaking pathological (codependent) relationships with the addicted patient. Th is approach leads to the disturbed personality and decompensation hypotheses, which were put forward by various authors to interpret some of the psychological characteristics of alcoholics' wives in the 1950s (Futterman, 1953;Кalashian, 1959).
Th e development of the codependency concept should be considered within the context of the social circumstances at the time. According to Haaken (1993), it originated from feministic ideas of gender equality and a medical concept focused on the presence of an unhealthy process within addicted patients' families.
According to feminist ideas, the negative psychological experiences of women having close relationships with addicts were considered to be caused by gender inequality. Th e aspects of family living associated with care and dependence were previously perceived as natural and socially approved. However, in the context of new changing social trends, such relations were considered to be inadequate and unhealthy, resulting in personal and micro-social harm, and therefore needing to be eradicated. Due to this, emotionally close, codependent relationships came to be recognized as at the very least inadequate, or even as an unhealthy situation which needed correction.
G. Dear asserts that the codependency concept is demeaning to women (Dear, 1996) in that it describes behaviors traditionally associated with the female role in the family, as that of an inadequate and disturbed personality.
In our opinion, this phenomenon refl ects the change in gender roles that has been taking place in the Western World. As suggested by Calderwood and Rajesparam (2014), at the time of the initial conceptualization of the codependency model, the stereotype of a woman implied the presence of such qualities as obedience and dependency, and her social activity was usually associated with taking care of others. Th e authors believe that nowadays women in Western society are more independent, both fi nancially and emotionally.
As some researchers note, the codependency concept relies on a model that focuses primarily on personal autonomy, which can confl ict with the cultural values of those social systems where an individual's behavior is determined by family traditions and where an interdependent caretaking style of family relationship is encouraged (Chang, 2012;Granello, & Beamish, 1998;Kwon, 2001).
During the 1990s and beyond, authors began to pay attention to the stigmatizing terminology of the codependency concept and lack of its empirical support for it (Lee, 2014;Dear, 1996;Harper, & Capdevila, 1990;Orford et al., 2013). Th e use of this pathologizing and stigmatizing terminology when working with addicts' family members has a negative eff ect on their psychological and social functioning (Lee, 2014;Orford et al., 2013). Characterizing women as codependent can signifi cantly damage their self-identifi cation, as this presumes their lack of ability to create mature, realistic, autonomy-based independent relationships. Such a characterization is basically a pseudo-objective social assessment of the personal functioning of women. It is perhaps more traumatizing as it is given by an authority fi gure, an expert in areas of drugs, alcohol, and other addictive substances. Th is is replicated numerous times in social environments such as self-help groups, which are ideally meant to provide help.
However, as Lee remarks, while displacement of the research focus away from patient's family's role in the development of an addictive disorder, protects the relatives from stigmatization, on the other hand it prevents gaining a coherent view of the family dynamics. Th is puts much of the blame for what is going on inside the family on the patients themselves (Lee, 2014).
In more recent times, the concept of codependency has become a lot less infl uential abroad and use of the term itself is becoming increasingly rare. Th e patients' relatives are more and more oft en referred to by terms that do not have such an obvious negative connotation, such as "aff ected family member, " "concerned family member, " "signifi cant other, " and so on. But in Russia, this theoretical construct still occupies a leading position.

Stress-oriented models
Even during the period of the apparent dominance of the codependency concept, there existed alternative approaches to understanding the psychology of the addicted patients' relatives. At the core of these concepts is, fi rst and foremost, the concept of stress. As early as the 1960-70s, studies were performed which focused on the origin of stress and the reversibility of the disorders that were seen in the addicts' relatives. In particular, the studies focused on the wives of those suff ering from alcoholism (Edwards et al., 1973;Kogan, & Jackson, 1965).
However, the data that did not fi t into the pathologizing notion about addict's relatives' defi ciencies -the methodological basis of codependency -were easily assimilated by the stress concept. Th is resulted in the codependency construct itself becoming less precise and consequently increasing the number of people whose behavior was described in codependency terms. Th e most radical opinions expressed by authors who agreed with this concept declared all those who interacted with the addict to be codependent, including those who were brought up in a family where one of its members had a marked disorder of a diff erent genesis (Schaef, 1986;Wegscheider-Cruse, 1985).
Currently, the stress-oriented approach is increasingly determining the theoretical comprehension of the psychology of addicts' relatives internationally. Interaction between a family member and an addict is looked at through the theoretical frame-work of chronic stress models, where stress, strain, adaptation, and coping serve as the categories analyzed.
Among the evidence-based stress-oriented models widely used in work with addicts' relatives, one should mention the Stress-strain-coping-support model (SSCS). UK policy documents report this model to be eff ective in decreasing drug and alcohol addiction's negative consequences for society and addicts' families (Velleman, 2010).
Within this model, interaction between a family and addict is considered a stress factor that can cause strain on family members, leading in some cases to somatic and/ or psychic disorders. In this case, the social support received by the addict's family serves as a buff er, and such mediation is capable of greatly relieving the negative impact of the addict's disease (Orford et al., 1998;2013).
One of the central elements of the SSCS model is the typology of the addict's relatives' coping behavior suggested by the authors. In this typology, Orford and his colleagues distinguish three principal diff erent family reactions to the addict's disease. Th ese include standing up to it, "putting up with it, " and becoming independent. (Orford et al., 2013).
Th is typology was originally derived from a cross-cultural study of coping behavior strategies of addicts' relatives carried out by the authors in England and Mexico (Orford et al., 1998). Coping behavior was estimated by Orford and his colleagues according to coping reactions recorded in a previous study. Th e qualitative and quantitative analysis, and in particular the factor analysis of results achieved by Orford's team, identifi ed diff erent possible reactions of the relatives living with a drug or alcohol addict. Th e analysis resulted in identifying three main factors called engagement, tolerant-inactive, and withdrawal (Orford et al., 2010).
It is curious to note that the presented construct is closely associated with instinctive theories of response to a threat such as "beat, " "standstill, " or "run. " Such a description of how addicts' relatives cope with the disease seems to be too simplistic.
Th e factor the authors called engagement combined strategies representing the family members' eff orts to change the addict's behavior. Th is factor included emotional coping -the emotional expression toward the addict; control -the attempt to limit the alcohol and drug use; and assertive reaction -a clear and calm position toward the addiction and support for the addict. A combination of assertive and supporting coping was described by the authors as one refl ecting family decisions as to which behavior of addicted family member was acceptable and which was not. Such forms of coping could motivate the addict to stop the substance abuse and/or to seek medical treatment.
According to Orford, tolerance-inactivity factors included strategies such as selfsacrifi ce and acceptance. Examples include attempts to forgive addicts, inactivity manifested by empty threats, the absence of any demands on the addict, and eff orts to keep the peace by any means.
Th e withdrawal factor which Orford described as bipolar contains strategies aimed at avoidance and independence and represents attempts to keep a distance from the addict by focusing on other interests and needs. Strategies of support are included in this factor with a negative loading (Orford et al., 2010, Velleman, 2010. While estimating the eff ectiveness of the interventions based on the SSCS model (known as the 5-Step Intervention), the authors interpreted the total reduction of the coping used by addicts' relatives as representing positive change. Th is reduction was primarily due to a decrease in the use of strategies involving active interaction between the family and the addict, such as engagement and tolerance-inactivity (Copello et al., 2000;2010a;Velleman et al., 2011). In some sampling groups, interventions performed were followed by an increase in withdrawal strategies.
From this we can conclude that spontaneous activity by relatives aimed at fi ghting the disease and supporting the addict was considered "unhealthy" by the authors (Copello et al., 2000, p. 482). It is important to note that attempts to cope with the disease may look like self-sacrifi ce when performed in close family relationships, and that family support can play a signifi cant role in the addict's recovery.
At the same time, a family member's increased independence and greater insistence on his or her own needs and rights, which are components of the withdrawal means of coping, are considered by the authors as chiefl y positive changes in the dynamic of the caretaking relative-addict relationship.
Such an evaluation is also underpinned by the illustrative material showing the quality analysis data. Th is is where family members demonstrated how they could withdraw from the addicts regardless of their condition, or even completely separate from them (Copello et al., 2000;2010a;Velleman et al., 2011). Evidence for the usefulness of the 5-Step Intervention can be seen by the fact that, even when family members considered that their substance-abusing relative had either not improved or had deteriorated, they still showed a signifi cant decrease in symptoms and coping behaviors (Velleman et al., 2011).
Th e authors conclude that the fewer coping reactions, the more positive changes there are, since most attempts to cope with the situation, particularly by way of engagement and tolerance, are unhelpful for family members' experience and health (Copello et al., 2010a;Velleman et al., 2011).
Orford and his colleagues emphasized the multidimensionality of coping strategies and warned against perceiving any of the strategies as dysfunctional or functional without referring them to a specifi c life situation. But, as we can see, at the core of the considered program is the assumption of absolute personal autonomy as a tool to obtain self-realization. Th is proposition should sound familiar because of its similarity to the codependency concept.
It is necessary to note that aft er the 5-Step Intervention, the relatives' symptom levels had only fallen to the level of those experienced by the sample of psychiatric in-patients and day-patients (Velleman et al., 2011).
One question that arises from this is why the number of symptoms refl ecting relatives' distress is still extremely high if non-adaptive coping strategies such as engagement and tolerance-inactivity associated with pathological symptoms, refl ect reduced engagement and emotional detachment from the addicted family member.
We believe that the problem lies in the existing methodological gap. When describing family members' reactions, Orford et al. consider the addicts' relatives to be passive recipients adjusting to the stressful conditions of life which are fully determined by the patients' behavior. At the same time, the relatives' behavior is constructive at its base, and is aimed at helping the patient recover from the disease. Th is refl ects the relatives' active role in the transformation of their environment and attempt to eliminate the main source of pathological stress. Underestimation of the relatives' active position leads to a lack of knowledge about the conditions and the factors associated with the success or failure of their active involvement in the patient's life. Th is subject is considered to be beyond the scope of the concept.
Th e contradiction between understanding the relative as a suff erer, a passive recipient in stressful circumstances, and the relative's actual position of a caregiver who gives assistance to his/her addicted relative and struggles with the illness, creates a methodological gap. Th is gap requires the implementation of a new special category for resolving existing contradictions. In our view, this could be the notion of engagement within the concept of burnout.
Deprecation of informal caregivers' eff orts, as observed in the fi eld of addiction treatment, can cause a blockage of personally meaningful activities and become one of the potential sources of the addicts' relatives' burnout. It is precisely this burnout, in our opinion, that results in the remaining psychopathological symptoms that are described in Orfords' studies.
In other words, a principal orientation toward separation or withdrawal of relatives from an addicted loved one interferes with those relatives' basic emotional needs to provide love and care for someone close to them. To fulfi ll this need is at least as important for the addicts' relatives' self-realization as is the need to achieve abstract personal autonomy. Th erefore, today's core idea of the necessary transformations in patient-caregiver relations should be revised to take into account the need for the active engagement of relatives in the addict's struggle against the disease, and in maintaining the well-being of an addicted family member.
It is necessary to note that a change in the distance between the chronically ill relative and informal caregiver is not specifi c for addictive disorders. Increase of the symbiotic tendencies in caregiver/care-recipient relationships is a natural reaction that certainly requires the attention of specialists. However, the presence of symbiotic tendencies is not any reason to deny the constructive personal activity of relatives aimed at supporting chronically ill family members, and cannot be overcome by mechanistically adopting opposite to symbiotic relationship forms of behaviors.
Nevertheless, the important achievement of the stress-oriented approach, compared to the codependency approach, is the partial de-stigmatization of the addicts' relatives, who are no longer considered dysfunctional and decompensated, but as normal people in a diffi cult life situation. Th is results in a signifi cant shift of scientifi c and research focus toward the experiences, diffi culties, and requirements of family members caring for addictive patients.
In the framework of the stress-oriented approach, the family experience of caregiving is also frequently conceptualized as a "burden. " Th e term "burden of the family" was fi rst mentioned by the American sociologist Treudley (1946) and refers to the consequences for those who care for severely disturbed psychiatric patients.
In psychiatry and somatic clinical practice, empirical studies of the informal caregiver's "burden" began in the 1960s (Hoenig, & Hamilton, 1966) and are actively ongoing to the present day (Yasuma et al., 2021).
Systematic research of the "burden" of addicts' relatives only began to be undertaken in the fi rst decade of the 21st century (Biegel et al., 2007). Purposefully study-ing the diffi culties resulting from having an addicted family member, the authors described various conditions, including emotional problems, fi nancial diffi culties, stigma, violence, and poor mental health (Di Sarno et al., 2021).
Despite the high relevance of studying and systematizing the diffi culties experienced by relatives of patients with addictive disorders, the theoretical construct of "burden" does not provide a holistic view of the processes in the lives of people involved in interactions with addicted loved ones. Ignoring the underlying group dynamic relationships of family members and group norms associated with the socio-cultural context and personal characteristics of caregivers, makes it impossible to form a complete picture so that the necessary psychological assistance can be provided. Additionally, the concept of "burden" is poorly defi ned and can't be measured accurately (Gérain, & Zech, 2019;Mosquera et al., 2016). So, the "burden" concept corresponds to the early stages of developing the burnout concept and focuses only on the negative aspects of caregiver/care-recipient interactions. It can be considered a link in the process of working out a comprehensive methodological framework for studying the addicts' relatives as informal caregivers. Th e concept of "burnout" can serve as a theoretical basis for such work.

Challenges of burnout concept's integration into the sphere of addictive disorders
As we have seen, the concept of burnout is considered an important principle in explaining the psychology of family members caring for chronically ill patients. Nevertheless, any research on burnout, besides our own studies (Bocharov et al., 2019;Shishkova et al., 2021a,b,c), has been non-existent in the area of addictive disorders, despite the evidence that family members take an active part in the care of addicts.
In our opinion, the main reason for the lack of studies is a methodological confl ict that has not yet been articulated by the scientifi c community. Th ere is a confl ict between the theoretical models which have been used for describing the psychology of addicts' family members for a considerable time, and the constructs developed to assess the impact of informal caregiving, which have become relevant since the cultural transformations of the last few decades.
In analyzing the described shift in understanding the psychology of addicts' relatives from codependency models to stress-oriented approaches, we should mention that these changes are due to the infl uence of various psychotherapeutic paradigms. Th e popular psychodynamic approach, with which the explanatory codependency models are associated, has gradually been replaced by the dominance of the cognitive-behavioral approach. One of the important foundations of this approach is the concept of stress.
Th e low economic effi ciency of psychoanalysis and its branches was one of the factors leading to ignoring the relatives of addictive patients, as they were seen as needing psychotherapeutic care in their own right. During this period, addicts' relatives organized various self-help groups such as the "Co-dependents Anonymous" community, an organization which has spread throughout the world.
As the cognitive-behavioral approach advanced, psychotherapeutic care became increasingly economically measurable and aff ordable. Th is ultimately led to the pos-sibility of its use as the main means of working with the family members of addicted patients. Th is was particularly the case in dealing with their irrational beliefs and maladaptive coping strategies. Currently, the special psychotherapy provided to relatives of addicted patients in many European countries is conceptual (Velleman, 2010).
Our analysis of the existing approaches to the study of relatives aff ected by addictive disorders allows us to point out changes in perception and attitude toward such relatives. Th ese changes are refl ected in the gradual reduction of stigmatization and the consideration of relatives as normal people in a diffi cult life situation.
Despite the fundamental diff erence between the initial message of the stressoriented models, for example the SSCS, and the codependency concept, there is a signifi cant similarity between the two approaches in understanding the causes of the dysfunction of addicts' relatives. In both approaches the root of the problem is located in their loss of autonomy. Accordingly, the restoration of optimal functioning is achieved in the separation of informal caregiving relatives from the care-recipient patients.
In addition, both concepts coincide in postulating the fundamental non-constructiveness of the interaction between the addict and caretaking family members, as well as the tendency to exclude relatives of the addicts from the caregiving process. According to the codependency concept, preoccupation with their own problems (personal dysfunctionality) determines the impossibility of family members performing the functions of caregivers. From the standpoint of the stress approach, the vulnerability of addicts' relatives to the infl uence of stress also basically excludes them from performing this role. One could agree with this, but given the fact that the real function of caregiving is performed by relatives, and that the anosognosia typical of addicts oft en leads to a lack of articulation of the very need for care, the family members are actually the only ones who want to and are able to provide care for their chronically ill relative.
Th e stigmatizing stereotype in perception and attitude toward addicts' relatives has substantially determined the defi cit-oriented approach currently observed in the fi eld of addiction research and treatment. Th is approach is characterized by focusing solely on the destructive elements of the "informal caregiver-addicted patient" relationship dynamic, and underestimation of relatives' willingness, experience, and knowledge in care for their addicted family member. Th e existing situation causes signifi cant delay in the awareness of the addicted patients' relatives as informal caregivers and prevents integration of the burnout concept, frequently used for evaluation of caregiving impact, into the fi eld of addictive disorders.
Th e personal activities of relatives in various forms of care directed to the maintenance of the well-being and fi ght against the disease of the chronically ill family member, are usually supported by specialists in the somatic and even psychiatric clinics. However, in addiction treatment, they encounter signifi cant resistance. Th is resistance is associated with the stereotypes in the evaluation of interactions between the addict and their relatives. Th is type of relationship is traditionally considered as a dysfunctional and mutually destructive one.
In the somatic clinic, where the existing patient's illness does not actually depend on the psychological functioning of the family, there is no stigmatizing idea about the impact of relatives on the emergence and maintenance of the pathological process. Th e term "caregiver" has become widespread here. Th is term refl ects the social shift s that determine the perception of chronically ill patients' relatives as those performing socially necessary functions, and their participation in treatment and rehabilitation is regarded as a key element in achieving successful results.
Th e peculiarities of the course of psychiatric diseases, in particular, the need to maintain compliance with medication and monitor the patient's condition for their timely hospitalization, have led to acknowledging the importance of engaging families of mentally ill patients as active participants in the therapeutic process. Such engagement is carried out despite the oft en-expressed stigmatization of this group.
Th e necessity of providing opportunities for family members to discuss treatment options and acquire awareness and information concerning addiction and the support available is already recognized by addiction service professionals (McDonagh, & Reddy, 2015). However, this should only be considered as an initial step to an eff ective partnership between relatives and professionals.
For the successful integration of the burnout concept into empirical and interventional studies of the addicts' relatives, total de-stigmatization of this group of informal caregivers is required; this implies a holistic view that includes not only the dysfunctional aspects, but also a notion of the constructive activity (engagement). In keeping with empowerment ideas, we should recognize the close relatives caring for the addict as equal participants of the treatment process, and enable them to become collaborators in their sick relatives' treatment decision-making.

Discussion
In recent years, the concept of burnout has assumed considerable prominence in the research of family members caring for chronically ill patients. By applying this concept, one can systematically examine both external factors -such as the burden relative to the severity and duration of the case -as well as the internal ones. Examples would be the social attitude, self-esteem level, and the degree of symptoms of depersonalization. Th ese factors can determine the eff ect of giving care on the caregiver. Studying the mechanisms of family caregivers' burnout, as well as development of prevention programs, are important both for caregiver and care-recipient. Th e chronically ill patient might be left without the assistance of family members because caregiving relatives' burnout causes them to be negligent. Th is negligence could cause the patient to succumb to their disease and result in fatality.
Th e current realities of life, results from continuing deinstitutionalization, increasing life expectancy, and the growth of chronic diseases, make it necessary to support the care provided by relatives of the chronically ill and create conditions for its enhancement and optimization. In this regard, the investigation of informal caregivers' burnout is an actively developing area, which is refl ected in the studies of burnout phenomena in relatives of somatically and mentally ill children and adults (Gerain, & Zech, 2019;Roskam et al., 2018;Norberg, & Green, 2007;Lebert-Charron et al., 2018;De Souza Alves et al., 2019).
Research in the addiction fi elds is markedly lacking in this respect. In the available literature, our own studies appear to be the only research on burnout in relatives of patients with chemical addictions such as alcoholism, opioid addiction, psycho-stimulant use disorder, and non-substance addiction such as gambling (Bocharov et al., 2019;Shishkova et al., 2021c). Th ose investigations were preceded by the development of a theoretical model and specialized assessment tool called the "Level of Relatives' Emotional Burnout" (Shishkova et al., 2021a,b).
For too long, clinical psychology and addictology have focused solely on the harmful consequences of stress caused by close relations with addicts and have thus confi ned the understanding of the behavior of addicts' relatives to a defi cit-oriented model.
A signifi cant sign of coming changes in understanding the interactions between an addict and their relatives is the usage of the term "caregiver, " observed in the literature during last decades (Copello et al., 2010b;Maina et al., 2021). In the fi eld of addictive disorders, the need for the direct supervision of the physical or mental health of the patients may be less obvious than that of other groups with chronic diseases. However, the severity and consequences associated with the long-term use of drugs or alcohol may require a strong response from the family members. Th is would be aimed at ensuring the addict's physical well-being as well as overcoming the current crisis that the patient is experiencing. Some family members could decide that they have no other option but to take on caring roles, even if they have no desire to (Velleman, 2010).
It is important to note that the reasons for this unwillingness are exhaustion or disappointment in the addict (Velleman, 2010). In our opinion, a similar picture can be observed in the family members of the patients suff ering from other chronic diseases and directly refl ects the processes associated with burnout.
Th e use of the term "caregiver" and corresponding theoretical context for understanding the psychological issues arising in the families of addicts are necessary steps to realizing and evaluating the constructive aspect of the activities of addicts' relatives. In this context, family caregivers are not considered to be obstacles but rather people who assist the professionals in the treatment of the patient.
As researchers in the fi eld of parenting children with chronic illness note, parents bring unique elements to the decision-making process, i.e., "the personal element versus the scientifi c part" (Jerrett, 1994(Jerrett, , p. 1054. Relatives value the healthcare professionals' expertise. However, they believed that their own experience and knowledge of their child's care should be recognized too (Coffey, 2006). For the successful achievement оf compliance with treatment, informal caregivers' views and contributions need to be taken into account.
Th e need of the addicts' relatives for active engagement in treatment and rehabilitation is not suffi ciently supported in the framework of current treatment programs. Th e constructive personal activities of caretaking relatives are refl ected, in particular, in their attempts to unite in peer-based social support communities. An example of such an association is the community named "Learn to Cope" (LTC), which was formed in Massachusetts in 2004 (Kelly et al., 2017) in the context of the increasing epidemic of opiate overdose. LTC was organized by a group of parents of drug addicts who shared their experience of fi ghting against the disease of a loved one. For example, they shared experiences relating to information about various treatment and rehabilitation programs and the diffi culties encountered in the process of obtaining insurance for treatment. Th ey invited specialists to conduct psycho-educational and training programs. Unlike groups based on the ideological assumptions of codependency models, an active supportive and protective position of the concerned relative towards the patient is encouraged here (Kelly et al., 2017).
On the one hand, application of the burnout concept as an important methodological principle allows us to reformulate many psychopathological phenomena regarding the family members of addicts. On the other hand, it expands the prospects of psychotherapy by giving an opportunity to conduct interventions improving relatives' functioning as caregivers.
Re-evaluation and change of the usual image of relatives formed in the fi eld of addiction treatment, opens up the possibility for a new understanding of the phenomena previously described as pathological manifestations of the personality and family disturbance (codependency). We refer to the family members' cynicism towards the patient, sense of bitterness, hostility, and contempt. Additionally, the relatives' increasing indiff erence to the outcome of the disease, the sense of uselessness and helplessness and the decrease of vital energy, in our opinion, should be understood as the result of long-term ineff ectiveness of the work of an addict's informal caregiver to overcome their loved one's disease in an environment of stigmatization. Similar phenomena are repeatedly described by various researchers among substance abuse treatment counselors and are interpreted within the framework of the burnout concept (Rapid Response Service, 2019). However, the direct transfer of the symptoms established within the burnout construct in work conditions to the fi eld of the psychology of the addictive patients' family has seemed to be impractical. Th is is because it does not take into account the various motives that determine the interaction between informal caregiver and addicted care-recipient. In other words, it is necessary to study how the patterns of burnout manifest themselves in the context of the specifi c group family dynamics.

Conclusion
Th e main goal of the present work was to identify the barriers and benefi ts of applying the burnout concept in the context of the relationships between addicts and their relatives. We believe that such implementation will contribute to the improvement of current models for studying the psychological issues arising in families aff ected by additive disorders, and will lead to the development of a deeper understanding of the complex problems and needs being experienced by family members taking care of addicts.
Th e fi rst obstacle to overcome is the stigmatizing image of patients' relatives as dysfunctional, passive recipients merely adjusting to the stressful and challenging circumstances. Such an image is now more or less dominant in the majority of theoretical models that serve as the basis for the development of programs used in addiction treatment. Th e urgent need for a paradigm shift to destigmatize addicts' relatives does not mean neglecting the specifi cs of the relationships between the caregiver and the care-recipient, due to the diagnosis-associated picture of the disease. Symbiotic regression manifested in the reduction of the distance between the patient and caregiver is typical for the initial stages of any disease. Th ere is no doubt that such regression can progress and take pathological forms which require correction. Th is pathological symbiotic relationship has been described in both the clinical treatment of addictive and mental disorders and has been called codependency and emotional overinvolvement, respectively.
Additionally, approaches that consider the psychology of chronically ill patients' families from the standpoint of the systems theories of family functioning should not be forgotten. Based on the ideas in these systems models, the presence of the disease in one of the family members may be necessary to maintain the family's pathological homeostasis. In this situation, the chronically ill family member acts as a patient who has taken on a diffi cult role for themselves. However, the implementation of a systemic approach requires the involvement of all the patient's family members in the therapeutic process. Th is also demands devoting a signifi cant amount of time to reconstruct the family situation before conducting subsequent psychotherapy interventions.
At the present time, clinicians are mainly focusing on reducing the symptoms of informal caregivers' stress and trauma, and have failed to support their relatives in their beliefs and need to give love and care to chronically ill loved ones. Such beliefs and needs, in turn, could serve as protective factors vis-a-vis caregivers' burden and burnout. To form a holistic view of the processes in the family of a chronically ill person, including a patient with addiction, it is necessary to take into account not only such potentially psychopathologizing processes as chronic stress, symbiotic regression, family burden, and burnout. Th ese contribute to the development of the psychological crisis, but it is also important to consider the constructive aspects of the informal caregivers' personal eff orts to overcome the illness and maintain the wellbeing of their relative. Th is approach will allow us to form a notion about the optimal meaningful activity of the individual, which is necessary to sustain a balance between the desire to provide maximum support to the sick family member on the one hand, and the caregivers need for self-actualization and identity preservation, on the other.
Insuffi cient research on the constructive personal activity of the addicted patient's family members under conditions of chronic stress is due to the stigmatizing attitudes that lead to a narrow understanding of the psychology of the addicts' caregivers. It is also due to the lack of an appropriate methodological framework and ability to measure how the construct of "engagement-burnout" should be quantifi ed.
In conclusion, we would like to say that the authors of this work do not deny the signifi cance of the phenomena described in other conceptual models, but are striving to provide a fuller context for investigation of the current situation in the families of addicts. Th e lack of a holistic, consistent understanding of what is occurring with informal caregivers of patients with addictive disorders oft en leads to signifi cant distortions in treatment goals and methods, signifi cantly reducing the quality of services provided to the patients and their relatives.
